Small patch to fix up some stuff!

Note: Don't forget that if you have the itch.io app then only the files that need updating will be downloaded rather than having to redownloadt the entire game!

Changelog:

• Changed the music in the Earth Kingdom Arena and the Southern Water Tribe Arena;
• Slight crowd sound effect in the Earth Kingdom Arena;
• Now you can actually hear the combustion explosion from far away;
• Combustion effect now actually disappears for the client instead of replaying over and over again;
• You can no longer move WHILE casting combustion (seriously that was too OP and wasn't meant to work like that);
• Combustion will now care for if you chose the blue combustion;
• You can now rename your character again (woops).
